Add uploadProofOfPayment and improve file validation

Browse Source 
- Implemented uploadProofOfPayment function for per-bill proof of payment
  - Validates file size using MAX_PROOF_OF_PAYMENT_UPLOAD_SIZE_KB env variable
  - Validates PDF file type
  - Prevents duplicate uploads with existence check
  - Uses optimized database projection to minimize data transfer
  - Updates specific bill using MongoDB array filters

- Refactored file validation in updateOrAddBill
  - Moved validation before serialization for fail-fast behavior
  - Added configurable file size limit from environment variable
  - Added PDF type validation
  - Improved error messages with specific validation failures

- Updated serializeAttachment function
  - Changed return type from BillAttachment to FileAttachment
  - Added uploadedAt timestamp to attachment object
  - Removed unsafe type cast

- Code formatting improvements throughout
  - Consistent spacing and indentation
  - Better TypeScript typing

This completes the per-bill proof of payment feature implementation.
